I've just switched from Xtra (Go Large) to Xnet.
My sync speeds continue to stay the same.
Download rates/speeds stayed the same too.

International downloads are roughly 256kbps (ie. ~30Kb/s)
National downloads are roughly 1.5Mbps (ie. ~190Kb/s)

I'm not dissapointed with Xnet (anythings better than xtra) but is there any room for improvement?

Check this topic it may/may not help?

I moved to XNet from GoLarge and found a big increase in speed eg 1.6Mb/s to 2.5Mb/s

I found the customer response from XNet awesome, I was blown away.

Thanks.

I did one of those line tests so if anyone knows how it all works they can check my readings here:

Try using an NZ server to do test. https://www.speedtest.net has 2 NZ servers. Should get a more accurate result.

It is possible that you will see no big improvement going from Go Large to another ISP as your line may not be able to do any better. Or you may be attached to a conklin DSLAM which are limited to 2Mbit.

Yeah that too gave speeds at about 1.5 - 2Mbps.
I guess if it is the DSLAM then people in my neighbourhood should experience the same sort of quality dsl.

Is there nothing an ISP can do with my ports to increase the speeds a little?

Try and find a report similar to the following from your ADSL Router/Modem

03/05/2007 - 12:49:04 - EVENT = PHYSICAL  STATISTICS -
    Upstream Output Power = -38 dBm
    Upstream Noise Margin = +12.0 dB
    Upstream Attenuation = 1.0 dB
    Upstream Bits per Frame = 184
    Upstream CRC Errors = 0
    Upstream FEC Errors = 0
    Upstream HEC Errors = 5
    Downstream Noise Margin = +12.0 dB
    Downstream Attenuation = 1.0 dB
    Downstream Bits per Frame = 1502
    Downstream CRC Errors = 10
    Downstream FEC Errors = 0
    Downstream HEC Errors = 5
    Startup Attempts = 1


Noise Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. The higher the number the better for this measurement. In some instances interleaving can help raise the noise margin to an acceptable level.

6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with little or no synch problems* (but see note below)
20dB-28dB is excellent
29dB or above is outstanding

* Note that there may be short term bursts of noise that may drop the margin, but due to the sampling time of the management utility in your modem, will not show up in the figures.

Line Attenuation
Measure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB the better for this measurement.

20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues

DSL Rate ***/tx/rx/Rate
The actual service data rate that your ISP has provisioned.

Attainable Line Rate
This is the maximum rate at which your modem can connect to the DSLAM if there was no service provisioning limiting the bandwidth. The higher the number the better.

Occupancy
Occupancy is the percentage of line capacity used. Each DSL line is capable of a certain maximum speed or "capacity" dependant on line distance and other varying factors. The occupancy is an expression of your current sync rate setting over your maximum capacity. There are occupancy rates for both upload and download. The lower the figure, the better. Because of error correction and other factors in the DSL protocols, a margin is required so that a connection can be maintained under varying line conditions. If the occupancy approaches 100%, any interference can cause the ADSL sync to be lost. A useful measurement to monitor when sync problems occur. [AFAIK the billion SNMP utility does not give a direct measurement of occupancy :-( ]

(with due acknowledgment of the other sources/forums that this info was gleaned from)

These are the only details I could pull out from my modem:

Attenuation Downstream: 31.0dB
Attenuation Upstream: 56.0dB
Connection Rate Downstream: ~2024 Kbps
Connection Rate Upstream: ~160 Kbps


Before Go Large my speeds would get upto 3.8Mbps (Connection Rate Downstream).

Ok do a speed test on XNet

http://speedtest.xport.co.nz/

Try Global Speed Test
https://www.speedtest.net/

Also try Xtra's
http://www.jetstreamgames.co.nz/speed/index.html


They should all report roughly the same download speed. Post results.

Check there is an ADSL Splitter on each telecom socket that has a phone connected

Have you had a chat with XNet technical support?

Hey Wooly,

I appreciate your help.
It seems connecting to xnet has made my speeds much worse.  No I have not spoken to xnet yet because I thought I'd give the change over a few days...But tomorrow I may call them.
Here are the results:

Xnet Speed Test:
Download: 760kbps
Upload: 97.4kbps
QoS: 85%
Round Trip Time: 88ms
Max Pause: 52ms

Global Speed Test (Auckland Server):
Download: 508kbps
Upload: 125kbps
Latency: 98ms
Distance: 50 mi

Xtra (500kb test):
Download: 705.3kbps

Xtra (1Mb test):
Download 628kbps.

Yip Contact XNet Technical Support

NZ'ers love to connect and so does Telecom apparently (sry just listening to and ad in the background)

Maybe worth emailing XNet with all you've gleaned so far

eg previous speeds and what you've tried so far plus this thread

What time of the day are you doing your speed tests? It could also possibly be that you are on a mini dslam type unit.

I am doing these tests at various times of the day including after midnight (to avoid peak traffic), they all tend to reveal speeds that are approximately the same.
